GI.GObject.Objects.ParamSpecVariant
Description
A ParamSpec
derived structure that contains the meta data for GVariant
properties.
When comparing values with paramValuesCmp
, scalar values with the same
type will be compared with variantCompare
. Other non-Nothing
variants will
be checked for equality with variantEqual
, and their sort order is
otherwise undefined. Nothing
is ordered before non-Nothing
variants. Two Nothing
values compare equal.
Since: 2.26
Synopsis
- newtype ParamSpecVariant = ParamSpecVariant (ManagedPtr ParamSpecVariant)

- toParamSpecVariant :: (MonadIO m, IsParamSpecVariant o) => o -> m ParamSpecVariant
Exported types
